APC Smart-UPS On-Line, 5kVA, Rackmount 3U, 230V, 6x C13+4x C19 IEC outlets, Network Card, Extended runtime, W/ rail kit, 6-year warranty

The APC Smart-UPS On-Line SRT5KRMXLI-6W is a 5 kVA double-conversion uninterruptible power supply (UPS) in a 3U rack/tower-convertible form factor. Designed for data centers and server rooms, it provides continuous, conditioned power to connected equipment through 10 AC outlets (C13 and C19) and a sealed lead-acid battery pack. Typical backup time at full load is approximately 4 minutes; the unit supports scalable runtime with plug-and-play external battery packs and user-replaceable, hot-swappable batteries for reduced downtime.

Advantages

The SRT5KRMXLI-6W offers true online double-conversion topology for high-quality power conditioning and frequency/voltage regulation without depleting the battery. Network and local management options include 10/100 BaseT connectivity, serial port, SmartSlot for management cards, and compatibility with InfraStruXure Manager. Built-in intelligence features—such as intelligent battery management, temperature-compensated charging, automatic self-test, predictive failure and battery-failure notifications—improve battery life and enable proactive maintenance. Additional features like green mode for improved efficiency, automatic internal bypass, resettable circuit breaker, and generator compatibility enhance reliability and serviceability.

Suitable for

• Server rooms and rack-mounted IT equipment
• Data centers and network closets
• Business-critical applications that require continuous power conditioning
• Environments needing scalable runtime and remote UPS management

How to use

Install the UPS in a rack or place it as a tower unit according to the provided mounting instructions. Connect critical equipment to the UPS AC outlets (C13/C19) and plug the UPS into a grounded utility power source. Configure network or serial management options if remote monitoring or firmware updates are required. For extended runtime, attach compatible external battery packs; hot-swappable and user-replaceable batteries allow battery service without shutting down protected loads. Perform periodic automatic self-tests and review battery notifications to schedule maintenance.

Recommendations

Place the UPS in a temperature-controlled environment, keep ventilation clear, and follow manufacturer guidelines for battery replacement intervals. Use the green mode for higher efficiency when full redundancy is not required and enable network management to receive predictive failure and battery-failure notifications for timely maintenance.
